规定了超声波检测设备的要求，以及使用A扫描演示对热处理铁素体钢铸件（厚度大于等于15 mm）指定区域进行检测的方法。铸件壁分为三个区域，并规定了三个应力水平的验收标准。附录提供了本标准的使用指南、不连续性的性质和识别指南以及不连续性的尺寸确定程序。

Sets out requirements for ultrasonic testing equipment and methods for the testing of specified areas of heat-treated ferritic steel castings (15 mm or greater in thickness), using A-scan presentation. The casting wall is divided into three zones and acceptance criteria are specified for three stress levels. Appendices provide guidance on the use of the Standard, guidance on the nature and identification of discontinuities and procedures for the sizing of discontinuities.
